Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
46 words
A tearing aid for oriented materials comprising an oriented material having a fold and a group of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 2
Dependent Claim
46 words
A tearing aid for oriented materials comprising an oriented material having a fold and a group of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 3
Dependent Claim
50 words
A tearing aid for packaging material comprising at least one oriented material having at least one fold and a grOup of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 4
Dependent Claim
50 words
A tearing aid for packaging material comprising at least one oriented material having at least one fold and a grOup of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 5
Dependent Claim
62 words
In a laminated packaging material, a tearing aid comprising at least one oriented material providing a lamination of the packaging material and said material having at least one fold and a group of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 6
Dependent Claim
62 words
In a laminated packaging material, a tearing aid comprising at least one oriented material providing a lamination of the packaging material and said material having at least one fold and a group of adjacent minute porelike punctures in said material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 7
Dependent Claim
63 words
In a laminated packaging material, a tearing aid comprising a plurality of oriented materials providing laminations of the packaging material, said oriented materials having a common fold and each of said oriented materials having a group of adjacent minute porelike punctures with said groups extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 8
Dependent Claim
63 words
In a laminated packaging material, a tearing aid comprising a plurality of oriented materials providing laminations of the packaging material, said oriented materials having a common fold and each of said oriented materials having a group of adjacent minute porelike punctures with said groups extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 9
Dependent Claim
40 words
In a laminated packaging material, a tearing aid as claimed in claim 4, wherein each of the punctures of one of said oriented materials is offset relative to each of the punctures of a further one of said oriented materials.
Claim 10
Dependent Claim
55 words
In a package of a material including at least one oriented material, a tearing aid comprising a fold in said package and a group of adjacent minute porelike punctures in the oriented material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 11
Dependent Claim
55 words
In a package of a material including at least one oriented material, a tearing aid comprising a fold in said package and a group of adjacent minute porelike punctures in the oriented material with said group extending on opposite sides of said fold for a relatively narrow width of said oriented material from said fold.
Claim 12
Dependent Claim
31 words
In a package of a material including at least one oriented material, a tearing aid as claimed in claim 6, wherein said punctures are closely grouped together in a geometric pattern.
Claim 13
Dependent Claim
31 words
In a package of a material including at least one oriented material, a tearing aid as claimed in claim 6, wherein said punctures are positioned along the length of said fold.
Claim 14
Dependent Claim
31 words
In a package of a material including at least one oriented material, a tearing aid as claimed in claim 6, wherein said punctures are each expanded portions of said oriented material.
Claim 15
Dependent Claim
42 words
A package comprising a tube of a material including at least one oriented material and a group of adjacent minute porelike punctures in a relatively small portion of said oriented material for assisting in the starting of the tearing of said tube.
Claim 16
Dependent Claim
42 words
A package comprising a tube of a material including at least one oriented material and a group of adjacent minute porelike punctures in a relatively small portion of said oriented material for assisting in the starting of the tearing of said tube.
